How do you graph using the intercepts for #-x-7y=14#?

1 Answer

Axis intercept values are when either #x# or #y# values are 0.

Explanation:

Because your equation is a linear function, the two intercepts can be calculated as follows:

Sub #x =0#
#-x-7y=14#
#-(0)-7y=14#
#-7y=14#
#y=-2#
#:.x#-intercept is #y=-2#

Sub #y =0#
#-x-7y=14#
#-x-7(0)=14#
#-x=14#
#:.y#-intercept is #x=-14#

Having this two points, simply draw a straight line between the intercepts, extrapolate it to infinity and you will get your graph! Hope this helps!
